80 * \brief Reload asterisk modules.
81 * \param name the name of the module to reload
83 * This function reloads the specified module, or if no modules are specified,
84 * it will reload all loaded modules.
86 * \note Modules are reloaded using their reload() functions, not unloading
87 * them and loading them again.
89 * \return Zero if the specified module was not found, 1 if the module was
90 * found but cannot be reloaded, -1 if a reload operation is already in
91 * progress, and 2 if the specfied module was found and reloaded.

96 * \brief Register a function to be executed before Asterisk exits.
97 * \param func The callback function to use.
99 * \return Zero on success, -1 on error.
101 int ast_register_atexit(void (*func)(void));
104 * \brief Unregister a function registered with ast_register_atexit().
105 * \param func The callback function to unregister.

110 * \brief Register the version of a source code file with the core.
111 * \param file the source file name
112 * \param version the version string (typically a CVS revision keyword string)
115 * This function should not be called directly, but instead the
116 * ASTERISK_FILE_VERSION macro should be used to register a file with the core.

121 * \brief Unregister a source code file from the core.
122 * \param file the source file name
125 * This function should not be called directly, but instead the
126 * ASTERISK_FILE_VERSION macro should be used to automatically unregister
127 * the file when the module is unloaded.
129 void ast_unregister_file_version(const char *file);
132 * \brief support for event profiling
133 * (note, this must be documented a lot more)
134 * ast_add_profile allocates a generic 'counter' with a given name,
135 * which can be shown with the command 'show profile <name>'
137 * The counter accumulates positive or negative values supplied by
138 * ast_add_profile(), dividing them by the 'scale' value passed in the
139 * create call, and also counts the number of 'events'.
140 * Values can also be taked by the TSC counter on ia32 architectures,
141 * in which case you can mark the start of an event calling ast_mark(id, 1)
142 * and then the end of the event with ast_mark(id, 0).
143 * For non-i386 architectures, these two calls return 0.

150 * \brief Register/unregister a source code file with the core.
151 * \param file the source file name
152 * \param version the version string (typically a CVS revision keyword string)
154 * This macro will place a file-scope constructor and destructor into the
155 * source of the module using it; this will cause the version of this file
156 * to registered with the Asterisk core (and unregistered) at the appropriate
162 * ASTERISK_FILE_VERSION(__FILE__, "\$Revision\$")
165 * \note The dollar signs above have been protected with backslashes to keep
166 * CVS from modifying them in this file; under normal circumstances they would
167 * not be present and CVS would expand the Revision keyword into the file's
